It happens – and if you’re a Windows Insider running any of the mobile builds it probably happens a lot more than you’d like. Sometimes the Windows mobile OS can freeze so deeply that its totally unresponsive to on-screen taps and pokes.
When that happens you need to fully reset the device (i.e., reset to factory defaults) using an arrangement of hardware button presses and holds that may seem more like the safety sequence for launching a nuclear missile than resetting a phone.
Here’s the sequence:
- Press and hold the Volume down and Power buttons at the same time until you feel a vibration. This usually takes 10-15 seconds.
- Just as you feel the vibration, release both buttons, but then immediately press and hold the Volume down button until you see a large exclamation mark.
- When the exclamation mark appears, press the following four buttons in this order:
That’s it. This sequence may work for some other Windows phone types, but there’s no guarantee. For those non-Lumia devices, check the web site of the manufacturer for support information on device resets.
